Question

For example this array has 5 element.

int saffet[] = {0,2,4,6,8};

And this has 2

int saffet[] = {0,2};

How can i get such as above?
(question is maybe simple because I’m learning java new)

Answer 1

Yup, it’s easy 🙂

int length = saffet.length;

Note that it’s recommended that you keep the type information together when declaring a variable (or parameter, return type etc) – while your declaration is correct, this is preferred:

int[] saffet = { 0, 2, 4, 6, 8 };

See chapter 10 of the Java Language Specification for more details on arrays.
